Abstract

A graphical input and display system having a user interface for selecting object(s) to be operated on by the system includes input devices permitting a user to select and establish image object(s) received from various image input sources. A processor, connected to the system, receives requests for various image element selection operations and also accesses a memory structure. The system memory structure includes a user interaction module, which allows a user to select image elements without pre-selecting an element selection mode, as well as data memory.

Claims

1. A graphical input and display system having a user interface for selecting image objects to be operated on by the system, comprising:

image object input means for entering said electronic image objects onto a display means;

user input means for receiving user selection commands;

a processor, connected for receiving requests for image object selection operations and for accessing a memory structure;

a user interaction module for selecting image objects without pre-selecting an object selection mode, wherein said object selection mode comprises a plurality of selection modes including rectangle drag mode, freeform pat mode, a polygon enclosure mode, and clicking or tapping on an element; and

data memory means.

2. The graphical input and display system according to claim 1, wherein said user input means comprises an electronic mouse.

3. The graphical input and display system according to claim 1, wherein said user input means comprises a stylus.

4. A method for utilizing a user interface on a graphical input and display system having user input means, image input moans, a processor, and a user interaction module for selecting image objects without pre-selecting an object selection mode for selecting objects to be operated on by the system, comprising:

receiving a user input selection;

automatically determining the selection mode, wherein said selection mode comprises a plurality of selection modes including rectangle drag mode, freeform path mode, a polygon enclosure mode, and clicking or tapping on an element of said input selection; and

performing the selection operation.

5. The method for utilizing a user interface on a graphical input and display system for selecting image objects to be operated on by the system according to claim 4, wherein said user input selection comprises a mouse click or stylus tap event.

6. The method for utilizing a user interface on a graphical input and display system for selecting image objects to be operated on by the system according to claim 5, wherein determining the selection mode of said input selection comprises:

selecting the object if said click or tap event is preformed on an image object;

initiating the path/rectangle mode if said click or tap event is not performed on said image object; and

initiating the polygon input mode if a second click or tap event is performed.

7. The method for utilizing a user interface on a graphical input and display system for selecting image objects to be operated on by the system according to claim 4, wherein said user input selection comprises a mouse or stylus drag event.

8. The method for utilizing a user interface on a graphical input and display system for selecting image elements to be operated on by the system according to claim 7, wherein determining the selection mode of said input selection comprises:

evaluating the path of said mouse or stylus drag event;

displaying a drag rectangle if said pat is a clear rectangle selection gesture;

displaying a drag path if said pat is a clear freeform path; and

displaying both a drag path and a drag rectangle if said path is an ambiguous selection gesture.

9. The method for utilizing a user interface on a graphical input and display system for selecting image elements to be operated on by the system according to claim 4, wherein said user input selection comprises a mouse release or stylus lift event.

10. The method for utilizing a user interface on a graphical input and display system for selecting image elements to be operated on by the system according to claim 9, wherein determining the selection mode of said input selection comprises:

evaluating the path drawn prior to said mouse release or stylus lift event;

selecting the objects by a rectangle if said path is evaluated to be a clear rectangle selection gesture; and

selecting the objects enclosed by a freeform path if said path is evaluated to be a freeform path selection gesture.

11. The method for utilizing a user interface on a graphical input and display system for selecting image elements to be operated on by the system according to claim 10, further comprising highlighting the region enclosed by said rectangle or said freeform path.

12. An article of manufacture comprising a computer usable medium having computer readable program code embodied in said medium which, when said program code is executed by said computer causes said computer to perform method steps for selecting image elements without pre-selecting an clement selection mode for selecting objects to be operated on by the system, said method steps comprising;

receiving a user input selection;

automatically determining the selection mode of said input selection, wherein said selection mode comprises a plurality of selection modes including rectangle drag mode, freeform pat mode, a polygon enclosure mode, and clicking or tapping on an element; and

performing the selection operation.

13. A memory for storing data for access by a program being executed on a computer for invoking object selection operations without pre-selecting an element selection mode for selecting objects to be operated on by the system, said memory comprising:

displayed objects data structure stored in said memory;

selected region data structure;

selection gesture data structure, wherein said selection gesture data structure comprises a plurality of selection modes including rectangle drag mode, freeform path mode, a polygon enclosure mode, and clicking or tapping on an element; and

selected objects data structure.
